January 3, 2012 – LONDON – Governments of the world’s leading economies have more than $7.6 trillion of debt maturing this year, with most facing a rise in borrowing costs. Led by Japan’s $3 trillion and the U.S.’s $2.8 trillion, the amount coming due for the Group of Seven nations and Brazil, Russia, India and China is up from $7.4 trillion at this time last year, according to data compiled by Bloomberg. Ten-year bond yields will be higher by year-end for at least seven of the countries, forecasts show. Investors may demand higher compensation to lend to countries that struggle to finance increasing debt burdens as the global economy slows, surveys show. The International Monetary Fund cut its forecast for growth this year to 4 percent from a prior estimate of 4.5 percent as Europe’s debt crisis spreads, the U.S. struggles to reduce a budget deficit exceeding $1 trillion and China’s property market cools. “The weight of supply may be a concern,” Stuart Thomson, a money manager in Glasgow at Ignis Asset Management Ltd., which oversees $121 billion, said in a Dec. 28 telephone interview. “Rather than the start of the year being the problem, it’s the middle part of the year that becomes the problem. That’s when we see the slowdown in the global economy having its biggest impact.” The amount needing to be refinanced rises to more than $8 trillion when interest payments are included. Coming after a year in which Standard & Poor’s cut the U.S.’s rating to AA+ from AAA and put 15 European nations on notice for possible downgrades, the competition to find buyers is heating up. “It is a big number and obviously because many governments are still in a deficit situation the debt continues to accumulate and that’s one of the biggest problems,” Elwin de Groot, an economist at Rabobank Nederland in Utrecht, Netherlands, part of the world’s biggest agricultural lender, said in an interview on Dec. 27. While most of the world’s biggest debtors had little trouble financing their debt load in 2011, with Bank of America Merrill Lynch’s Global Sovereign Broad Market Plus Index gaining 6.1 percent, the most since 2008, that may change. –Bloomberg
